Javier Esposito

Javier Esposito and Kevin Ryan are two individual homicide detectives, but had they been written as Siamese twins, not much would have changed in terms of the show's trajectory. When they're not making jokes and offering a nice balance to Castle and Beckett's complicated dynamic, these partners are often given the very annoying task of getting statements from every person at a crime scene, despite the fact that there's an actual writer working with them now. Moreover, they are almost always sent to investigate something about the case that doesn't pan out, while Castle and Beckett head right to the source of the problem. We imagine they find this frustrating.
